Vayger the Gatekeeper is a character in Fallout: New California.
During the quests "Journey To The Deep"/"Battle in the Deep", the Star Player will be ambushed on a bridge in the Fissure of Sorrow inside Fort Daggerpoint.
Vayger begins a dialogue and gives the Star Player an offer to voluntarily surrender and join the Unity. Several attribute checks allow you to avoid capture and escape. If you surrender, the quest "The Master's Revenge" begins and Vayger accompanies the character to the cistern with FEV. You can ask him about super mutants and Project Brazil.
Vayger is armed with a unique minigun called the CZ57 Avenger.
Trivia[]
The Luck 8 option of asking for sky god help would have dropped an explosively hit nearby, very likely to kill Star player in the process. A fun option, but ultimately not a survivable choice.
